Morning Buck, What you posted sounds like what I need. I have a prop adapter designed to work on the left hand thread Echo crank, but it may be too small to work on a 48cc. It was made for the 23.6 engine. My problem with it is that the Adapter and prop washer are small, you would have to see it to know if it could be used or not. I do not have the machinery or the skills to use them and don't know any one who does. If you hear any thing from your friend or you can take it on , let me hear more from you.

Later george
